The BM32S2031-1 is the second-generation proximity sensing module. Compared with the ex-generation, it removes the LED indicator to make itself smaller. Its specifications are the same as the ex-generation and it can be compatible with the previous one.
Proximity is determined by detecting changes in reflection. The BM32S2031-1 integrates active infrared emission, reception, and optical mechanisms. It includes a long sensing distance (up to 100cm) and automatic learning of sensing distance.
The BM32S2031-1 provides two operation modes:
I/O mode: the output pin changes from high to low when the module detects an object. The default detection distance is 85cm, and users can easily change the sensing distance.
UART mode: the external MCU can read and write parameters through the UART interface and quickly adjust module characteristics. The I/O mode suffices for general usage cases.
